* builtins.c (expand_builtin_setjmp_setup): Update comment.

	* function.h (struct function): Move va_list_gpr_size,
	va_list_fpr_size, function_frequency to front of bitfields.  Add
	calls_unwind_init.
	(current_function_calls_unwind_init): New.
	* except.c (expand_builtin_unwind_init): Set
	current_function_calls_unwind_init not
	current_function_has_nonlocal_label.
	* reload1.c (has_nonexceptional_receiver): New.
	(reload): Use it and current_function_calls_unwind_init to
	determine whether call-saved regs must be saved.
